Boy in pot brownie school incident arrested

COSTA MESA, Calif. 
A 12-year-old Orange County boy who allegedly passed around a marijuana brownie at his school, sickening students, has been arrested after authorities say they found a bag of pot in his backpack.

Costa Mesa police say the boy was arrested Thursday at his home after Pomona Elementary School officials discovered the marijuana in a backpack he'd left at school. His name hasn't been released.

The boy was arrested on suspicion of possessing marijuana on campus and released into a parent's custody.

Seven students at the elementary school became sick on Tuesday after the boy allegedly gave them bites of a marijuana-laced brownie he brought from home. The kids had breathing trouble, nausea and vomiting. They went to a hospital but have recovered.
